A study was undertaken to determine the possibility of inducing paracoccidioidomycosis in mice exposed to the mycelial phase of P. Two strains of the fungus, designated FG and LA, were grown separately in media favoring the production of spores by the mycelial phase. These were collected and used for nasal instillation of cortisone treated-mice. Animals were observed for a period of 16 weeks and sacrificed periodically. The infection was not lethal.

Two of them correspond to the disseminated form with metastatic lesions at the oral mucosa; the remaining one, with important pulmonary bilateral lesions corresponds to the pure chronic pulmonary form of the disease which is recognized by the first time in the country.
No doubt, these clinical forms will be found much more frequently in the endemic areas of Latin America if serological surveys are developed in the near future.

They relate a case of a patient presenting a perineal lesion two years after the excision of a tumor caused by P. They comment on Mackinnon's pathogenic theory of South American Blastomycosis that presumes that lungs are the portal of entry of P. Thus, mucocutaneous lesions are secondary to a primary pulmonary localization by hematogenous route. This is a preview of subscription content, log in to check access.
Paracoccidioidomicosis: A proposito de 3 nuevos casos nacionales
Virulence and infectivity of nine strains of Paracoccidioides brasiliensis were investigated in groups of mice which were inoculated intranasally or intravenously, and some of each were treated with corticosteroids. Fatal infections were not often seen among untreated mice, but mortality usually occurred when corticosteroids were given, regardless of the route of fungus inoculation. Prior treatment did not uniformly increase the incidence of infection, however; only in the case of intranasally inoculated mice was this effect seen. Most strains appeared to be more virulent when administered intravenously, with the exception of a single strain which, under the influence of corticosteroids, repeatedly displayed greatest virulence when given intranasally. All animals that died early in the course of the disease, irrespective of route of inoculation, always had acute pulmonary lesions and usually no other organ was involved. Animals which died later or were sacrificed always had chronic lung lesions.
